I'm still reading through the site, second week of vacation and I have had a lot of time to steep in all this great information. One thing was keeping me up last night, aside from the usual, and that is I keep bumping into references about some CFS/ME folk trying and benefitting from antiretroviral meds. I read the summary on XMRV and get that was a dead end. But why in that case would antiretrovirals do anything at all positive for people with this condition? Example is this doctor and her daughter, http://www.x-rx.net/blog/ There also seem to be some politics around this question so pls forgive me if I'm treading old or tired ground. This may be a lot to ask. But if one of the more technically minded among you either provide a thumbnail overview of this, or - as it may be - simply confirm as George Carlin used to say "well, son, it's a mystery." I'd appreciate it. Many thanks in advance.
